Microbleed Detection in Traumatic Brain Injury at 3T and 7T: Comparing 2D and 3D Gradient-Recalled Echo (GRE) Imaging with Susceptibility-Weighted Imaging (SWI)

چکیده
Methods Twenty-four patients and three controls (21 men, 6 women, mean age 33.4 years, age range 19-54) were recruited and scanned on 3T or 7T GE Excite scanners. Five TBI patients scanned at 3T received a repeat scan 1 to 12 months after the first scan, for a total of 23 scans at 3T and 9 scans at 7T. Sixteen of the patients had mild TBI (Glasgow Coma Scale (GCS) 13-15), three moderate TBI (GCS 9-12), three severe TBI (GCS 3-8) and two of undocumented severity. The mean time from injury to MRI was 261 days (range 2 days to 3 years).

Susceptibility-weighted imaging (SWI) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. It is a new art which evaluates and exploits the properties of blood, iron and other tissues. It is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3D fully velocit...

متن کاملSusceptibility-weighted imaging is more reliable than T2*-weighted gradient-recalled echo MRI for detecting microbleeds.
BACKGROUND AND PURPOSE We investigated the sensitivity and reliability of MRI susceptibility-weighted imaging (SWI) compared with routine MRI T2*-weighted gradient-recalled echo (GRE) for cerebral microbleed (CMB) detection. METHODS We used data from a prospective study of cerebral amyloid angiopathy (n=9; mean age, 71±8.3) and healthy non-cerebral amyloid angiopathy controls (n=22; mean age,...
